Embodiment Construction

[0024] The present invention will be further described in detail below in conjunction with the accompanying drawings and examples. The following examples are explanations of the present invention and the present invention is not limited to the following examples.

[0025] Example.

[0026] Such as Figure 1-Figure 4 As shown, the grid device of the cylinder former of the paper machine includes a cylinder cage 1 , a grid forming wire 2 , a couch roll 3 , a mesh felt 4 , a cleaning drum 5 and a frame 6 .

[0027] The cleaning cylinder 5 is fixed on the frame 6 by bolts, and clear water is placed in the cleaning cylinder 5, which can wash the cylinder cage 1 and the grid forming net 2 to reduce dust and impurities on the grid forming net 2 and improve product quality. Offer hole on the cleaning cylinder 5, the rotary mesh cage 1 is installed in the hole, and the bottom of the rotary mesh cage 1 is soaked in water. When the rotary screen cage 1 rotates, the part of the rotary sc...

Abstract

The invention relates to a manufacturing method of heat-sealed type grid tea leaf and coffee filter paper and a grid device of a circular net forming device of a paper-making machine for the manufacturing method. The device comprises a circular net cage, a grid forming net, a couch roller, a net cloth blanket, a cleaning cylinder and a frame, wherein the grid forming net is sheathed outside the circular net cage, ad the couch roller is matched with the circular net cage. The method comprises the following steps of: (a) enabling 20%-50% of softwood pulp and 50%-80% of polypropylene fiber short yarn to constitute hot-melt fiber pulp, and enabling the hot-melt fiber pulp to form a wet paper page with a heat sealing function in an oblique net forming device; and (b) enabling 0-60% of abaca and 40-100% of the softwood pulp to constitute long fiber pulp of natural fiber, forming the long fiber pulp of the natural fiber in the grid device of the circular net forming device of the paper-making machine and forming the wet paper page with grid lines. The device has the advantages of high strength, better heat sealing strength, higher air permeability and fast leaching speed, and is suitable for packaging bagged tea and coffee with large packaging capacity.

Description

technical field [0001] The invention relates to a manufacturing method of heat-sealed grid tea and coffee filter paper, and a grid device of a paper machine cylinder former used in the manufacturing method, belonging to the papermaking industry. Heat-sealed mesh filter paper is mainly used in tea and coffee packaging machines to produce various tea bags and coffee. Background technique [0002] The heat-sealed tea filter paper of the prior art is also suitable for packaging various tea bags for tea and coffee. Its disadvantage is that when the bag is packaged at more than 5g / bag, if the packaging strength needs to be ensured, the quantitative amount of the filter paper needs to be increased. However, the increase of the quantitative amount of filter paper will cause the air permeability, leaching rate and leaching speed to decrease, which cannot meet the ideal application effect of large packaging. [0003] For example, the Chinese patent specification whose publication num...
